Abstract excerpt

Understanding the factors shaping parasite population structure is key to unravelling host-parasite coevolution and transmission dynamics. Respiratory mites of the genus Orthohalarachne (Acari: Halarachnidae) are obligate parasites infecting the respiratory tract of otariids, yet their population genetics remain largely unexplored. Here, we examined the genetic structure of O. attenuata and O. diminuata infecting...
